Abstract

OBJECTIVES:

To evaluate the prognostic role of pretreatment serum levels of soluble CD30 (sCD30) in patients with advanced stage classical Hodgkin's lymphoma (cHL) treated with adriamycin, bleomycin, vinblastine, and dacarbazine or equivalent regimens.

METHODS:

We identified 321 previously untreated patients with cHL who presented to the participating centers between 1985 and 2002, and had serum samples available for the determination of sCD30 levels.

RESULTS:

With a median follow-up of 72 months, the actuarial 5-year overall survival was 82%, and failure-free survival (FFS) was 71%. The median serum level of sCD30 was 65 U/mL (range: 1-2230), and was significantly higher (P < 0.0001) when compared with a group of 113 healthy controls (4 U/mL, range: 0-20). Increasing level of sCD30 was associated with a continuous worsening of FFS and OS, and patients with sCD30 >or=200 U/mL had a 5-year FFS of 39%. With multivariate analysis, sCD30, Ann Arbor stage, and lactic acid dehydrogenase were significant independent factors in terms of FFS. The association of the above-mentioned three independent prognostic variables could discriminate 22% of patients with 5-year FFS of 40%.

CONCLUSIONS:

Our data confirm the independent prognostic role of sCD30 in identifying the patients with high risk of treatment failure, and show that its association with other variables can recognize patients with FFS considerably lower than 50%.
